And then there are “continuations”. You find these in Scheme, not so much 
in other languages. They are a generalized control construct. They can be 
used to implement looping-with-multiple-exits, exceptions and coroutines, 
but not (easily) for arbitrary gotos.

In other words, you can consider them to be a generalized *structured* 
control construct.
